CALCULATING APPARATUS.

Application filed December 2, 1910.

To all wh'om it may concern:

Be it known that I, PAUL F. W. C. KRIP- PENDORF, a citizen of the United States, re sidin at Lynn, county of Essex, and State of assachusetts, have invented an Improvement in Calculating Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to calculating apparatus, and its object is to provide such an apparatus by means of which the area of material required to cut therefrom a number of shapes of various sizes may be readily and accurately determined.

The present invention, in one of its aspects, is an improvement upon the invention disclosed in Patent N 0. 1,166,528, granted to me Jan. 4, 1916. The general principles of the present invention are the same as those explained in the said patent. The present invention provides a calculating apparatus of this type in which the operative inecha: nisms have been improved and simplified so as to insure great accuracy under the most severe conditions of use.

The invention also involves provisions in the apparatus by means of which a plurality of calculations may be made simultaneously, thus enabling the area of leathers or materials required to out different parts of the same shoe, for example, to be calcu- The invention also comprises means'for securing an additional adjustment whereby the reading of the calculator may be varied to cover an additional factor, such, for example, as a change in the, quality of leather being used. y

The foregoing and other features of the invention will more fully appear from the accompanying description and drawings and will be particularly set forth in the claims.

The drawings represent a machine embodying the'invention comprising means for making two calculations simultaneously, cer-- Specification of Letters Patent.

Serial No. 595,212.

the chief portion of the mechanism shown in Fig. 2; Fig. 4 is a side elevation, partially in cross section, of the mechanism shown in Fig. 2; Fig. 5 is a detail in vertical cross section of the carriage for the wheel driven by the actuator; Fig. 6 is a side elevation, partially incross section, through the carriage and showing the superimposed indicators. Fig. 7 is a view in elevation of the uppermost indicator disks.

The apparatus comprises a series of indicators similar to those shown in my afore said patent, these indicators being so constructed that they represent in their operative effect a series of ratios such as those ex isting between various lengths or sizes of shoes which, as explained 1n my aforesaid patent, are proportional to .the areas of the shoe parts having the said lengths and being all of the same width. Theseindicators are shown as circular disks superimposed, the top disk being indicated at2, and the bottom disk at 3. These indicators are located upon a common central axis, shown as a post 4 carryingat its upper end fixed thereto a disk 1, and are mounted for rotary or angular movement on the said post. he units of angular movement of the several disks are so indicated or determined as to have the aforesaid ratios to one another, and in the form shown in the drawings the diameters or circumferences of the disks vary according to the given ratios. The several indicators are provided with the equal peripheral graduations marked by the studs 5, three of which are illustrated in Fig. 1, and locking levers 6, one of which is illustrated in Fig. 1, are provided for locking the disks together in the manner described in my aforesaid patent, the uppermost indicator 2 being locked to the fixed disk 1 by a lever carried by the fixed disk, and the succeeding lower indicators being locked to the one below by similar levers.

The lowermost indicator 3 is made fast to a base 7 presenting a flat bottom surface 8. hereintermed the actuator,.. and is provided with arms 9 supporting a 'handwheel 10. It will thus-be seen that when the indicators are arranged with the locking levers set at the zero points, if any lever be depressed and the indicator thereby unlocked e moved around to the left, all the indicators below or following it will move at the same time and to the' same extent, so

that the movements of the actuator 7 resulting from successive movements of the indicators are always cumulative. It will also be seen that when the indicators, or any of them, have been displaced to the left from the position shown in Fig. 1, they may all be returned to the zero position by grasping the hand wheel 10 and turning it in the reverse direction, as in my aforesaid patent. The total angular movement of the actuator as determined by the indicators is measured by the wheel 11 which, as in my aforesaid patent, is rotated by frictlonal contact with said actuator and is carried by a shaft 12. The desired calculations are effected, as explained in my aforesaid patent, by adjusting or moving the wheel 11 radially of the actuator 8 so as to cause it to/be rotated a greater or less distance as required by the same angular movement of the actuator.

In the present invention the wheel 11 and ,its shaft 12 aresupported in a carriage 13 guided by ways 14. The framework of the carriage at its ends 15 and 16 extends down between the ways, and a cross pin 17 at the end 16 extends beneath the over-hanging projection of the ways. A U-shaped lever 18 is fulcrumed at 19 to the frameflof the carriage and has its lower end 20 in line with the ways 14. This lever 18 is normally elevated by grasshopper springs 21 engaging it and the frame of the carriage and a suitable handle 22 projects from the lever. The construction is such that the spring 21, normally acting to raise the U-shaped lever 18 and bringing the ends of the lever 20 against the top of the ways 14, throws the carnage upwardly at its end 15 and about the pin 17 to bring the wheel 11 into frictional contact with the surface 8 of the actuator 7.

When it is desired to shift the carriage the I from the shaft and indicating in square feet on a reading dial 24 the area of the leather. The shaft 12 also carries a wed e shaped cam 25 rotatably adjustable thereon and set so that its sides incline at equal angles to the vertical when the reading dial is at zero. The U-shaped lever 18 is provided with adjustable pins 26 having their points equidistant from the verticalplane of the shaft 12. Upon the depression of the lever 18 these points 26 coming into contact with the inclined sides of the wedge-shaped cam 25 insure the position-- ing of the shaft 12 to cause the dial of cyclometer to indicate zero. The object of this feature of the apparatus is to insure that in operating the calculating apparatus the readings shall always start at zero. If for any reason there should be any lost motion or failure to carry the indicators all back to their exact zero pointthere would be a slight movement away from the zero of the dial 24, but as the carriage 13 can only be moved by depression of the lever 18 the depression of this lever is made at the same time to insure the setting of the dial at Zero.

It is essential that the movement of the carriage 13, carrying wheel 11, radially of the actuator 8 shall be steady, subject to no lost motion and capable of the finest de-' gree of adjustment. To secure these ends I have devised the mechanism shown in the drawings. This mechanism comprises a graduated wheel 30 mounted to turn on a fixed axis constituted by a stud 31 and connected by metal bands to the carriage 13, so that any movement of rotation imparted to the wheel 30 causes directly and positively a longitudinal movement of the carriage 13 upon its ways.

As shown, a bracket 32 is rigidly secured by screws 33 to the frame work or base of the apparatus and the curved bracket 34 is similarly secured by means of screws 35, it being understood that the ways 14 are fixed upon the base or frame of the apparatus, so that these ways 14 and the brackets 32 and 34 occupy fixed positions with re-' spect to each other. The brackets 32 and 34. are also rigidly connected by a radially disposed brace member 320 carrying the stud 31 which is held therein by a set screw 321, and locked to the bracket 34 by screws 322. See Fig. 3. The stud 31 projects upwardly through the bracket 32 and upon this stud the graduated wheel 30 is mounted to rotate. The wheel 30 is skeletonized as shown in the drawings, and carries rigid therewith a segment 37. The carriage 13 has connected therewith by a pivot 27 above the pin 17 a bar 28 sliding upon the way 14 and, consequently, moving longitudinally with the carriage but not partaking of the vertical movement of the carriage about the pin 17. This bar 2-8 is of substantially the same length as the segment 37. A metal band 38, preferably in one continuous piece as shown, is attached at one end 39 to the bar 28, passes thence along the segment 37, along the bar 40 pivoted at 41 to the wheel 30, thence around the hub of the wheel along the second bar 42, pivotedat 41, thence along the segment 37 beneath the end 39 to the opposite end of the bar 28 Where it is made fastat 43. A set screw 44 carried by a projection 45 bears against the center of the band and secures it to the hub of the wheel, while other set screws 46 carried by the projections 47 bear against the pivoted arms 40 and 42, thus enabling a very deli cate adjustment of the longitudinal position of the carriage 13 with respect to the wheel 30 to be made.

The wheel 30 is provided on its upper face andnear its periphery with a series of graduations shown in that part of the apparatus now being described as running from 1 to 22 and indicating when the machine is to be used for calculating the area of shoe parts in square feet, the dec mal point not being indicated. Thegraduations therefore run from .1 to 2.2 square feet and these graduations appear through an opening in the base of the machine, as shown in Fig. 1. It is usually necessary to indicate'fractional portions of the unit indicated by said graduations on the wheel 30 and to secure this indication in an accurate and distinct manner I have provided a fractional scale plate 50 graduated .decimally and so arranged that when it is moved to bring a given decimal thereon into line with the graduationsof the graduated wheel 30, the wheel 30 will be given a corresponding fractional rotation. ,As shown, the scale plate 50 is pivotally mounted at 51 on the radial plate 60. This radial plate 60 is mounted to pivot or swing about the stud 31 and it carries at its forward edge a scale 61 which, in the case of an apparatus suchas that illustrated for use in connection with shoe parts, bears the designations of the difi'erent shoe widths and, as shown, running. from AA to EE. The fractional scale plate 50 is connected to a segmental plate 52 by a metal band 53 attached at its ends to the segmental plate and passing around the hub 54 of the plate 50. The segmental plate 52 rests and slides upon the radial plate 60 and it carries rigidly connected therewith by the pins 55 a thin plate 56 containing an aperture of just suflicient size to allow the figures appearing upon thewheel 30 and fractional scale 50'to appear therethrough and indicate the desired reading. The plate 56 partakes, therefore, of any 'movementgiven to the segmental plate 52 but the aperture 57 in the base is made sufliciently large so that whatever position the segmental plate 52 may take the reading through the aper ture in the plate 56 will always be visible.

The wheel 30 is provided on its periphery with a series of holes 301 spaced to correspond with the numbers appearing on the face of the wheel and the segmental plate carries a spring-pressed plunger 58 which locks the wheel and segmental plate together by entering one of the said holes figure on the Wheel 30 appears through the aperture 56, when the plunger is allowed tospring in and lock the wheel 30 to the segmental plate 52. The fractional movement of the wheel 30 is secured by swinging the fractional scale plate 50 about its hub and thus through the metal band 53 moving the segmental plate 52 which is rigidly connected t-o the wheel 30 by the plunger 58 and the fractional amount moved is indicated by the figure on the frac-- tional scale plate 50 appearing in the aperture 56. 'To secure this result with accuracy the hub 54 of the fractional scale plate 50 is provided with a projecting arm 59 upon which the adjusting and locking set screws for the metal band 53 are mounted and which carries a spring-pressed plunger 591,

adapted to enter one of a series-of holes in the periphery of the segment block 592, fastened by set screws 593 to the radial plate 60. The holes in the periphery of the segment block 592 correspond with the graduations on thexscale plate 50, and in the construction illustrated represent tenth parts of the graduations on the Wheel 30. It; will be observed that the longitudinal movement of the carriage '13 and the consequent movement of the wheel 11 in a path radially of the actuator 8 is obtained entirely from the rotation of the wheel 30. The rotary adjustment of this wheel already described is insufficient to take care of all the factors required in the operation of this form of device, because it is necessary to provide for an unequal variation, and for that purpose I provide the mechanism shown.

. The brace member 320 is slotted radially from the axis 31 as indicated at 323, and a block 324 is mounted to slide in said slot and carries rigidly connected therewith and extending vertically upward a post entering a. cam groove 71 in the lower face of the wheel 30. This cam groove extends in a course regularly and progressively distant from the axis of the wheel 30. An auxiliary radial plate slides at its forward end upon the bracket 34 and is pivoted between the said bracket cured together by a spring-pressed plunger:

83 sliding in the plate 80 and entering one of a series of holes 62 in the depending segmental flange 63 of the plate 60.

The plate 80 carries at its forward edge and secured thereto by set screws 8 1 a pointer plate 85. F or a purpose to be described later, a scale plate 90 is mounted on top of the auxiliary radial plate 80 and carries on itsfacedesignations such as the numbers 2, 3, 1,'etc., these numbers being arranged so that either may be brought into radial juxtaposition with the designations on the scale 61. inner end is bent downwardly and apertured to correspond with the hole 62 so that by withdrawing the plunger 83 sufficiently the scale plate 90 may be shifted to any desired position. a

The foregoing description of the wheel 11 driven by the actuator 8, the carriage for sliding the wheel radially of the indicator disks, and the mechanism 'for securing the desired radial adjustment of the carriage applies equally to the mechanism illustrated at the right hand side of Fig. 1, which mech-' anism is, save in the proportion of some of its parts, in all lespects a duplicate of the mechanism described. In this second mechanism, shown at the right hand of Fig. 1, the wheel is indicated at 111, the carriage at 131, and the apertured plate through which the indicating figures appear at 560.

By arranging the apparatus with a plurality of wheels, such as 11 and 111, driven by the same actuator and by providing for an independent radial adjustment of these wheels with respect to the single actuator, and by providin 'means for indicatingv and setting the radia position of each wheel independently of the other, it is possible upon one setting of the superimposed indicators, or indicating disks, to make a plurality of separate calculations afiecting the same subject; for example, in the case of the measurement of the area to be allowed for the cutting of shoe parts for which this machine is particularly designed, one is enabled by the use of the machine illustrated to make the desiredv calculations with respect to two separate parts or sets of parts of the same shoes. For further example, in shoes comprised of patent leather vamps and kid tops the, area required to cut the Vamps of patent leather and the area to cut the tops of kid for any desired number and assortment of shbes can be calculated simultaneously by using one mechanism for each, and these mechanisms being adjustable separately enables the proper and different constants to be employed in each case.

The operation of the entire calculating apparatus disclosed in this application and the features of which are made the subject of this invention will be readily understood by anyone familiar with my. aforesaid "patent. in the case of the present machine, as in the This scale plate 90 at its pointer recess of the scale plate 90.

case of that shown in the said patent, a table is first prepared showing the amount of leather which it is desired to allow for the cutting of the parts of one pair of shoes of a given size taking as a standard, such, for example, as in the present case, length 5, width D, which amount will be based upon, (1) an allowance for wastage, (2) the particular part or group of parts to be cut, (3) the particular style of the shoe, and (4) the kind of leather to be used. Such a table is based on the actual area of the shoe parts as determined by careful measurement and upon theparticular manufacturers experience and practice with reference to the allowances for wastage, and it may be in the following form:

Substantially the actual area of the respective parts may be found in square feet and decimals thereof by dividing the values given above by 100.

The foregoing table applies only to shoes of the width D, adopted for convenience as a standard. To modify the amount required according to the change in width, the calculating apparatus is adjusted by withdrawing the plunger 83 and shifting the position of the radial plate 60 and the auxiliary radial plate 80 until the letter indicating the desired width appears in file e foregoing table also applies only to shoes of the length 5, adopted as a standard, and in order to modify the amounts in accordance with the lengths of the shoes, the indicators 2, 3, etc., are made use of as explained in my aforesaid patent. The number of shoes is also taken care of by the extent to which these several indicators are rotated.

In some cases it is desirable to make a further modification by introducing another factor into the calculation. If, for example, a job lot of leather is purchased by a manufacturer and it is desired to allow more leather for the cutting of shoe parts by reason of the inferior quality of the leather, or if an extra high grade of leather scale plate 90. As shown in the drawings,

this scale plate is made with its pointer recess in line with the scale number 5, and when so set the operation of the machine will giveresults corresponding to the figures of the above table modified by (1) the widths of the shoes, (2) the lengths of the shoes, and (3) the number of the shoes in question. If now the plunger 83 be withdrawn and the scale plate 90 be shifted either to the right or to the left so as to bring a different number than 5 into the pointer recess of the plate 85 and then the said scale plate 90 be locked in this position by the return of the plunger 83, its pointer recess will have been shifted to the right or to the left and a new basis will have een established for determining the relative positions of the radial plate 60 and the auxiliary radial plate 80, because the letters on the scale 61 will now appear at the pointer recess in the scale plate 90 in a different radial position. By thus shifting the scale plate 90 the amount of leather required may be increased or diminished as desired.

The operation of the apparatus now needs little further explanation. Assume, for example, that it is desired to calculate the area required to cut a certain number of pairs of -shoes having kid tops and patent leather Vamps, tips, and foxings. The handle 22 is depressed, causing the wheel 11 to be freed from contact with the actuator 8, and the cam 25 operated to insure the appearance of the zero points in the cyclometer 23 and, if desired, the wheelmay be locked in depressed position by the pin 29 entering the recess 290. If there is to be no special modification outside of the facts called for by the table the scale plate 90 is set with the number 5 showing in the pointer recess of plate 85. The plunger 83 is operated to lock the radial plate 60 and the auxiliary radial plate 80 together with the character 1) appearing in the pointer recess of the scale plate 90. The plunger 58 is then withdrawn and the carriage 13 slid along the ways 14:

until the integral parts of the required number in the table appears at the opening in the plate 56, when the plunger is allowed to spring back into the hole in the periphery of the wheel 30. The plunger 591 is then withdrawn and the fractional scale plate shifted until the required fractional part of the number appears in the aperture in the plate 56, when the plunger 591 is allowed to spring back into the proper hole in the segment block 592. The same procedure is followed with respect to the other set of mechanism at the right hand side until the proper number for the other parts of the shoe ap pears at the aperture in the plate 560. If the width of the shoe to be calculated is to be other than D, the plunger 83 in each instance is operated and the radial positions of the radial plate 60 and the auxiliary radial plate 80 shifted to bring the required width at the pointer recess in the scale plate 90. The wheels 11 and 111 are then released by withdrawing the pins 29 and are allowed to come into contact with the actuator 8, and the indicator disks are then operated as in my aforesaid patent according to the number of the shoes and their respective lengths, and thereupon the desired areas will appear in the respective cyclometers.

It frequently happens in practice, owing to the size of lasts used, or for other reasons, that it is desirable to cut the shoe parts one half size in length,smaller or larger, than the actual calculated amount. I provide for this contingency by shifting the scale plate 90 to the left or right, which I find in practice to give substantially this desired variation. If the operator were called upon to allow for the half size in length in operating the indicators mistakes would be liable to occur, while by shifting the scale plate 90 the operator can operate the indicators according to the size required and the desired allowance will be made automatically by the machine. To enable this to be done the scale plate 90 is marked with legends 1} up, 9; down, and when these marks are placed opposite the apertures in the pointer plate 85 the desired result will be secured.
